Iran is among the countries which id most vulnerable to natural disasters, especially earthquakes. This natural phenomenon creates a disaster in an area of Iran every few years and destroys the human and financial potentials of the country and it has also irreversible mental and emotional consequences. Due to the unexpected nature of most natural disasters and the need for rapid and accurate decision-making and implementation process, fundamental and theoretical basis has created a knowledge called crisis management. Bojnord city is the center of Bojnord town in North Khorasan province and is the largest city in the province. The city is one of the high altitudes of North Khorasan and is a mountainous region from the natural perspective. Based on census population in 2011, Bojnord has a population over 207,196 people. Bojnord is one of the cities that are located in a zoning with a very high relative risk. Moses Baba fault and Dubarar-tower fault of Bojnord are located in the immediate vicinity of city and in some regions the city is built along this fault. Faults in Bojnord have been the origin of devastating earthquakes in history and are able to work once again and threaten the city which determined the importance and role of crisis management and passive defense in earthquake more than ever. In addition to the potential threat, Bojnord faults has made clear the adverse consequences arising from the filling of Bojnord plain from human habitations and the development of the city towards the fault line at a distance of 150 meters and this has also attracted attention to passive defense two times more. Therefore, identifying risk zones (faults and earthquakes) in the city can show the vital artery in low risk decision areas and zones with low risk for the construction of temporary housing camps during the crisis. Bojnord is in a bowl surrounded by mountains and down the valley. 

Timing framework associated with catastrophes is one of the most important issues in crisis management. In such cases, being immediate has a considerable importance and web based real-time routing service as an important tool has a significant role in relief operations improvement. At this study, a web-based real time routing service based on open source technology has designed for 11^th district of Tehran aiming to efficiency enhancement of relief teams at emergency conditions. In this service ANP model was used to evaluate increasing interaction between the factors, and since the purpose of this study was to find the best possible routs between two nodes by non-negative weight according to the main distance factor, Dijkstra's algorithm has been chosen as a proper routing algorithm. Open source languages, format, libraries and software such as HTML, CSS, AJAX, GeoJSON, PHP, OpenLayer, PostGIS were also used to design the service and applying online weightings, blocking each piece of routes and re-routing procedure without blocked traffics, implementation of server-side processing and reducing the volume of the client-side’s operations, being under the browser’s surveillance, no need to install any software and the ability to use it on any operating system can be named. According to the obtained results, the path’s length and traffic’s volume variables have the most important role in target function formation (travel cost) therefore the specific path will be selected as the optimal path, with the minimized distance between the destination and the traffic volume. Depending on the traffic volume severity changes, the optimal extracted route will be changed and the system has such ability to apply online weighting in order to instantaneous routing to reduce losses.

In public organizations such as municipalities, the design and deployment of a performance and control assessment system can lead to the proper management of urban managers on the road to achieving goals, tasks, strategies and development plans and urban development, in accordance with the quality, cost and time desired. Therefore, this article attempts to study the satisfaction of urban performance in urban services by using the views of citizens of the city of Farouj. For this assessment, using theoretical studies, 21 types of urban services were selected in three sections: Technical, Public and Cultural Services. At the next stage, the questionnaire was designed based on these services. Then, 400 questionnaires were distributed among the citizens of the case study city. In the next step, 380 questionnaires were completely and correctly collected and entered into SPSS software. Finally, the results of the study were analyzed by statistical tests. The results of the research indicate that the average satisfaction rate of public services in the city of Farouj is 3.53, which can be said that the level of citizens' compliance with this service is in the middle level. The average satisfaction rate of technical services in the city of Farouj has been calculated to be 3.31, and the average satisfaction rate of cultural services in city of Farouj has been calculated to be equal to 3.5. The results of statistical analysis indicate that the level of significance is more than 0.05 in relation to four of the urban services. This means that in terms of the services of sports spaces, the collection and disposal of surface water, the quality of leisure travelers and the respect of the clients, the level of satisfaction of citizens is equal to the average. In relation to two indicators of pedestrian quality and public participation, the mean difference with the statistical test was calculated to be 0.16 and -0.19 respectively, which indicates that the satisfaction of these services is lower than the limit on average. In other indicators, citizens' satisfaction is above average

Quite a lot of people are employed in gas production and refining industry in IRAN. In case of weakness or lack of having an effective management, the associated companies will impose heavy damage to the country. In this regard, to achieve consistency and safety in IRAN, ascendancy of management in these companies is one of the main and effective attempts. In order to manage the crisis of technological hazards in south pars gas complex, this study presents a strategic model. To this end, firstly, a review of all research and previous studies is done. The statistical population of this study is 35 persons including managers, safety experts, HSE, and Passive Defense experts. Effective factors on technological hazards management is defined as: leadership and management, human resource, organizational culture, organization agility, organization systems, local infrastructures, production continuity and, continuum inspection is determined through an exhaustive investigation. Subsequently, a questionnaire using Delphi technique is prepared and conducted over the statistical population. The obtained data was analyzed with SPSS and AMOS software, and the results showed that among the other factors, human resource has more considerable effect on crisis management.

Accordingly, the economic index has the most impact, and the social indicator has the lowest impact. Based on the T test, the economic index is in the best position, followed by the management index, the social index, and the last rank of the environmental index. According to the Friedman test, the first rank index, the social index ranked second, and the environmental index ranked third.

Promoting urban livability and realizing a livable city are closely linked to how the urban management apparatus and institutions and organizations active in urban affairs function. Municipalities, as the most important coordinating body in urban affairs, have played a decisive role in solving urban problems and are responsible for the social and physical development of cities. In fact, municipalities have the main task of serving the citizens and play the most important role in improving the quality of life of citizens. The purpose of this study is to evaluate the viability level of Semnan city and analyze the problems of Semnan city from the perspective of different groups (officials-elites). The research method is descriptive-analytical and the research tool is a questionnaire. The validity and reliability of this research has been confirmed by the previous similar research and the opinions of the supervisors and advisors of the dissertation, the validity of the research tools. The internal validity of the instrument (questionnaire) is also shown through the Cronbach's alpha with a value of 0.84 for the questionnaires. The results showed that among the total biomarker indicators of Semnan city, from the point of view of elites and officials (with an average of 2.76), it was evaluated at a low level. Also, based on prioritization with ANP technique, "Improving Institutional-Organizational Capacity in Optimal Urban Management (R7)" with the highest score (07/357: 357) was identified as the best solution and in fact the main solution to deal with urban issues in Semnan. Also, the strategy of "integrated management between urban organizations to coordinate in the management of urban affairs (R6)" with (06/3366) was selected as the second solution.

River management, including strategies that effectively have an effect on the behavior. Geomorphological management, is the study of shapes, nature, and origin, processes of emergence, development and use of human and material composition of the Earth.  The assessment of river character and behavior in Stage 1 is based on analysis of the assemblage of geomorphic units (channel and floodplain landforms) along any reach. Arangeh River basin were identified in 1and 3 styles, including: Headwater, Gorge style in confined valley setting, planform controlled, floodplain bed, low sinuosity cobble, low sinuosity gravel, bedrock controlled sand, meandering gravel, unconfined low sinuosity cobble with Side stabilized, partly-confined low sinuosity cobble with Side stabilized, partly confined Asymmetric valley with cobble, , partly confined symmetric valley with cobble  ,Artificial bed.Geomorphic conditions of each of the styles were evaluated in the two stage of river style framework. at this stage of adjustment of Each style is determined to the confusion of peak flow by using criteria such as channel characteristics (size, shape, morphology Bank and plants channels), channel plan form (sinuosity, lateral stability, geomorphic units into the channel and River flood plain and plants) and features bed . Two Style had good geomorphic conditions (floodplain bed bedrock controlled sand, unconfined low sinuosity cobble with Side stabilized) show the potential of a good adjustment, and the reach has a good of potential adjustments are more sensitive to changes . In the fourth stage of rehabilitation is carried out in reach scales, basins and river basin based on forecasts of possible changes in the future and potential of Geomorphic River Recovery. Each style is proposed management priorities in accordance with the geomorphic and recycling potential.

Tehran metropolitan authorities have always tried to develop the most efficient model for managing Tehran metropolitan affairs. Currently, the Tehran city management model is the council-city model, according to which people elect the members of the city council by direct vote, and the Tehran City Council elects the mayor. Over the past years, and considering that the institutions and organizations in charge of managing and providing urban services have in some cases suffered from parallel work or even inconsistencies in tasks, there is a need to develop a model for integrated urban management. In this article, descriptive-analytical method has been used. This article is practical in terms of the purpose of the study. The purpose of this article is to achieve a model for integrated management of Tehran metropolis. The statistical population of this study is Tehran urban management experts for which 34 people were selected as a sample. The data collection tools of this research are interviews and questionnaires and the data have been analyzed using paired comparison and TOPSIS methods. As a result of this research, according to the identified challenges and using TOPSIS method, the efficiency of the developed research model (with the proposed name of service desk) compared to the current model of Tehran urban management has been confirmed. Also, the most important result obtained from comparative studies is that in the studied metropolises, all matters of governance and urban management are always under the command of one institution and parallel work has been avoided, which should also be considered in Tehran.

Proper urban management based on the right methods has always been a serious challenge for urban professionals and has been the subject of various discussions and studies over time. Each city, due to its specific characteristics, experiences special issues that are specific to the city and its surroundings, and in the meantime, creating a single model is not acceptable. Good urban governance is an important principle in urban management, which unfortunately In our country, it faces many obstacles. The present article has been done in terms of purpose, application-development and quantitative-analytical method, which first identifies the most important obstacles to the actual implementation of urban governance in the country and then examines these cases in the study area of ​​Garmadreh. The results show that the factor of lack of integration between different sectors of urban management with an average of 3.8 has the greatest impact on the lack of governance in the country. From the results of the first part, 4 basic effective indicators in the implementation of urban governance in the study area have been studied. In the executive level of Garmadreh city, in the field of accountability index of weakness factor in continuous and public supervision with an average rank of 5.38, in the index of rule of law rule, there are multiple, parallel, interpretable and sometimes contradictory laws with an average rank of 3.73, in the transparency index of factor of lack of access to information 4.56 And in the participation index, the factor of intense centralism and top-down management with an average rank of 4.48 have the greatest impact on the lack of proper implementation of urban governance in the city of Garmadreh.

 As it can take an efficient step towards the preservation and sustainability of such lands due to the preparation, implementation, and reformation of criteria. In District 9 of Isfahan Municipality, mismanagement in the preservation of ecological lands has destroyed gardens and agricultural lands, and has caused the loss of social unity of neighborhoods. Consequently, the study of ecotourism management in this region is of great significance. For this reason, in this paper, a model for ecotourism management with an emphasis on urban ecological textures is provided for District 9 of Isfahan Municipality. For this reason, first, the Star method has been used as a model for interviewing experts and relevant municipal experts in Isfahan city management. At that point, with the help of library investigations and field assessments, and implementation of the grounded theory method, 3 dimensions, 10 categories, and 35 subcategories are extracted from the data gained from the interview. The main dimensions are urban texture management (with categories legislation, planning, management of resources and control and supervision), the ecological texture (with the categories: protection and development and improvement), ecotourism (with the economic, social, environmental and cultural categories).

In this regard, the main purpose of this study is to investigate the role of non-governmental organizations in improving the urban management system of Tehran metropolis in six physical, functional, social, economic, environmental and institutional dimensions. The research method was descriptive-analytical and the data collection method was documentary and survey. The research tool was a questionnaire. The statistical population of the study was the citizens of Tehran and the sample size was 383 people. The data were analyzed using T-test and confirmatory factor analysis. The results show that the level of significance in all dimensions is lower than 0.05; Therefore, according to the average scores, NGOs in Tehran have mainly played a greater role in the social and environmental dimensions and in the economic and institutional dimensions in the form of an intermediary relationship between urban management and citizens. In the framework of confirmatory factor analysis, comparison of explanatory variance by six factors showed that social, environmental, functional, physical, economic and institutional factors have the highest variance in explaining the role of factors in the urban management system of Tehran. A total of 20 main factors in explaining the role of semen were confirmed; Thus, it was found that the Samanids, given that they are in direct contact with citizens, can accurately reflect urban issues and realities to the urban management system; For this purpose, it is suggested that first, according to their different functions, the subdivisions should be classified into specialized subdivisions on various urban issues, and also their position in the urban management system should be upgraded.

 The purpose of this study was to develop good governance indicators and criteria, evaluate good governance in integrated management of Kish, and provide strategies to promote integrated management of coastal areas with good governance approach. To accomplish these goals, firstly, by explaining the subject literature and reviewing the research background, an integrated coastal zone management model with a good governance approach was presented. The main criteria in this model are participation, legislation, accountability, accountability, central justice, transparency, efficiency and effectiveness, and community-centricity, each of which includes sub-criteria. Then, by using questionnaire and interviewing residents and experts, as well as by applying hierarchical analysis method, good governance status in integrated management of Kish was assessed. The final score of Kish by calculations was 2.53 (out of 5), indicating a relatively inadequate situation of good governance in Kish integrated management. Finally, solutions were presented to promote good governance in the integrated management of
